Individual marker styling inconsistent

Hi, thank you for making and working on such a wonderful plotting package.

For one of the projects I'm working on, I'm trying to style individual markers, however it's inconsistent when trying to target individual markers. For example I want to make the fourth point as full opacity (1) and larger (15) while the others are at 0.2 and size 10. I would expect "sample4" to be at full opacity, but it's "sample3". Am I doing something wrong?

test_data <- data.frame(
    x_data = c(2.8113, 5.8112, 7.3461, 15.5405, 16.3035),
    y_data = c(2, 2, 2, 6, 3),
    groups = c("group1", "group1", "group2", "group2", "group1"),
    samples = c("sample1", "sample2", "sample3", "sample4", "sample5")
)
plotly::plot_ly(
    test_data,
    x = ~x_data,
    y = ~y_data,
    mode = "markers",
    type = "scatter",
    color = ~groups,
    text = ~samples,
    marker = list(
        size = c(10, 10, 10, 15, 10),
        opacity = c(0.2, 0.2, 0.2, 1, 0.2)
      )
    )

produces the following plot

Thanks a lot in advance!

Riproducete l’esempio plot_ly fornito nel repository plotly.R e verificate come i vettori marker raggruppati vengono mappati sui punti tracciati. Confrontate lo stile marker visualizzato con i vettori size e opacity richiesti. Il lavoro è completato quando sample4 riceve size 15 e opacity 1, mentre gli altri campioni ricevono size 10 e opacity 0.2.
